I am trying to display a vertex marker for a QGIS Python plugin I am writing. I am getting a the following error...
'NameError: global name 'QgsVertexMarker' is not defined'
canv = self.iface.mapCanvas()
canv.setExtent(rect)
marker = QgsVertexMarker(canv)
marker.setCenter(QgsPoint(x,y))
canv.refresh()
What am I doing wrong?
You just need to import it from the qgis.gui module
from qgis.gui import QgsVertexMarker
